I see Ike showing his superior skill and strength for the onset and stopping the Rock in the middle rounds.
Yeah, what people can't seem to see is that Rahman has a respectable amount of boxing skills, and one thing Ike had was adaptability. This would've been a fun watch.
Rahman was good but I see him as being less skilled and not as powerful version of Ike. I think it would be an active fight from start to finish but I'd expect Ibeabuchi to get the better of most of the exchanges backing Rahman up at times and eventually Rahman would wilt and Ibeabuchi would finish him off.
